Embodiment Construction

[0015] Such as figure 1 As shown in the schematic diagram of the CT scan of the cross-section of the kidney, the blood containing the contrast agent in the examinee’s body has not yet entered the kidney at this moment. It can be clearly seen from the figure that there is no contrast agent in the abdominal aorta 1, and there is no contrast agent in the renal artery. (unmarked) there would be no contrast agent, and no trace of contrast agent in renal vein 2.

[0016] Such as figure 2 As shown in the schematic diagram of the CT scan of the kidney cross-section, the blood containing the contrast agent in the examinee’s body is about to enter the kidney at this moment. It can be clearly seen from the figure that there is a contrast agent in the abdominal aorta 1, and there is a contrast agent in the renal artery 2. There are traces of contrast agent.

[0017] Such as image 3 As shown in the schematic diagram of the CT scan of the kidney cross-section, the blood containing the ...

Abstract

The invention relates to a method for measuring blood circulation time of kidney by CT tracking and scanning. The time when the blood containing contrast agent appears in renal artery is observed and recorded on a CT tracking and scanning cross section image, and the time when the blood containing the contrast agent first appears in renal artery is recorded. The difference between the former time and the latter is blood circulation time of kidney. The method for measuring blood circulation time of kidney by CT tracking and scanning is noninvasive, including the steps of initially determining the positions of renal artery and renal vein on the cross section; injecting the contrast agent through the vein to display the blood flowing kidney in the image; and observing the image and respectively recording the time when the contrast agent appears in the renal artery on the cross section and the time when the contrast agent appears in the renal vein, wherein the time between the former time and the latter is the time for which blood enters the kidney from the renal artery and flows out of the kidney from the renal vein, namely the blood circulation time of kidney.

Description

technical field [0001] The invention relates to a method for measuring the blood circulation time of the kidney, in particular to a method for measuring the blood circulation time of the kidney with CT tracking scanning. Background technique [0002] The kidney is an important organ of the human body. Its basic function is to produce urine to remove metabolites and certain wastes and poisons in the body, and at the same time retain water and other useful substances through the reabsorption function, such as glucose, protein, amino acids, and sodium ions , potassium ions, sodium bicarbonate, etc., to regulate water, electrolyte balance and maintain acid-base balance. The kidney also has an endocrine function, producing renin, erythropoietin, active vitamin D3, prostaglandins, kinins, etc. It is also the degradation site of some endocrine hormones in the body and the target organ of extrarenal hormones. These functions of the kidneys ensure the stability of the internal envir...
